3 Sheets-Sheet 3 Attorneys United W68 A Patent MOLD Lucius B. Du Laney, Bellaire, Tex. -l-ApplicationrMarch-l 1954; SerialzNm-AIBZOM 1-1 Claim. (Cl. 25- 118) Thistinvention relates topipe-weights,.such-as are used stoprop'erlyanchor -pipes and conduits "in the bottom of .strearns and otherbodies of water an'dalso to -a novel 'tmold :"for use in manufacturing I the tpipe weights. I

The primary "object of the present. inventionhresides 'in :the provisionrofa pipe-weight of such construction as to eliminate the time and effort usually requiredu-in 'the placing of two halves of conventional pipe weights on the top =andbottom of theconduit'or piperandalso eliminating the numerous bolts ,Previously required to hold the conventional pipe weights together on the pipe.

The construction of this invention features a, pipe wei-ghhwhich is formed in two halves hingedly secured -together with wires embedded therein when the weights are-cast. 'Then, the halves of the concrete *weight are pickedrup with a boom, the sections .of the pipe weight opehed wide so that they can be loaded onto 'the'pipe Without difiiculty.

Another object of the inventionresides in theprovision of a mold for forming pipe weigh-ts :that" may "be used-to form both sections of the pipe -weight simultaneously,

while also providing means for forming the uneans for embedding the means hingedly securing the sections of the pipe weight together in the sections when they are cast.

Still further objects and features of this invention reside in the provision of a pipe weight that is strong and durable, simple in construction and manufacture, capable of being constructed from various readily available materials, and which is very eifective and practical in use. These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by these pipe weights and by the mold for casting the pipe weights, a preferred embodiment of the pipe weight and of the mold being shown in the accompanying drawings, by way of example only, wherein:

Figure 7 is an elevational view of the mold for casting 2,7 9-1 ,019 Fatented May 7, 1 957 2 10 generally designates a pipe or conduit whichis to be weighted by: means ofthe' pipe weight generally designated by reference numeral 12 whichcomprises the'present invention. The pipe weight 12 'is'forme'd from a'pair of substantially cylindrical sections 214and 16 having trustro-conical ends,'as at.l8 and'20. The-pipe Weight 12 may be cast from concrete, cast iron or any other suitable substance, but is preferably formedof concrete since such material is of satisfactory weight and com- :paratively iinexpensive.

while the lower. portions of the wear plates '22'and 24 reinforce'the concrete sectionsI14 and-16'when the opened plate isllowered into engagement with the pipe,'as is shown in Figure 3. It' isto benoted'that the sections 14 and 16 are 'not' quite completely semiwyclindrical,- but at the base of the sections 14 and 16,"they terminate short of abuttingeach other,"forming a'spac'e, as at 28, ther'ebetwe'en. Aligned recesses :30 and 32 are formedin the lower portions of thesections rl iand' 16 and recessed portions 34 and 36 o'figreaterdimensionsethan the recesses 30-and -32 are in communication :with' .th-e re'cesses 30 and 32. The recessed portions34and '36'are of substantial T-shape and the'recessed'area'of the lower'sections "14 and 16 which-include the recesseS SO-"and 34, and' 32 and 36 are thus substantially cruciform in'shape, forming' shoulders as at '38 and "40 against which metallic "-plates, .as at 42 and 44 rcanbearwh'en the sections 14 and 16 are clampingly held "together over --thepipe 10-by meansofa single bolt- 46. Embedded in-the sections l t and 16 in recesses 48 and 50 are a pair of eye members 52 and 54 which are adapted to be engaged by hooks or other suitable tackle 56 and 58 attached to a boom or other lifting apparatus.

The weights 12 are applied over the pipe 10 as follows. The weight 12 is attached to suitable cables carried by a boom or other lifting apparatus utilizing the eyes 52 and 54. The two halves of the weight 12 are hinged together with the wires 26 and thus open wide. They .are then lowered over the pipe 10 and when the weight 12 comes to rest on the pipe, the two halves automatically fold around it until they are in a position so that the single bolt 46 may be secured. It is to be recognized that the bolt is in a loosened position with the plates 42 and 44 optionally positioned thereon, and all that is necessary is to slide this bolt assembly into position where the plates 42 and 44 bear against the shoulders 38 and 40, at which time the nut 60 may be tightened. This eliminates the necessity of aligning holes in the various weight sections which must be done in conventional pipe weights.

Referring now to the mold for forming the concrete weights as is illustrated in Figures 7 and 8, it will be noted that the mold is formed from a pair of mold sections and 82 which have substantially U-shaped members 84 and 86 welded to the outer shells 88 and 90 thereof in such manner that a channel shaped member 92 can be used to hold the mold sections 80 and 82 together at those parts where the sets of core pieces 94, 96, 98, 100, 102 and 104 are located. It is to be noted that the core pieces 94 and 104 are utilized to form the recesses 34 and 36, while the core pieces 96 and 102 are utilized to form the recesses 30 and 32. Thus, the con1- bination of the core pieces 96 and 98 and 102 and 104 form the cruciform-shaped recessed portions of the mold sections. The core pieces 98 and 100 combine to form the space 28.

Between the mold sections 80 and 82 is a spacing plate 106 which has a guide 108 received between the U-shaped members 84 and 86. The spacing plate 106 is used for alignment of the mold sections 80 and 82. The outer shells 88 and 90 are each formed in parts, the shell 88 being divided into parts 110 and 112 hingedly secured to each other, as at 114, while the outer shell90 is formed of parts 116 and 118 hingedly secured, as at The outer mold shell parts 110 and 112 have core pieces 122 and 124 therein which are provided for the formation of the recess 50, and adapted to form a slot 126 for reception of the eye piece 54 which becomes embedded in the weight 12'once the fill has been poured into the mold. Likewise, core pieces 128 and 130 are welded or otherwise attached to the outer mold shell parts 116 and 118 and form a slot 132 for reception of outermold shell parts 112 and 118 are inwardly convergent, as at 142 and 144 to form the divergent surfaces on the upper portions of the weight sections 14 and 16.

' v has fully set, it may be removed from the mold and then The wear plates 22 and 24 can be positioned within the mounted on a suitable base 154, and a mix, preferably of concrete, but possibly of cast iron or other suitable material is poured into the confines. As soon as the mix allowed to cure as necessary.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equiva lents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

A mold forforming pipe weights'compn'singa pair of mold sections each including a substantially semi-cylindrical outer mold shell and'a substantially semi-cylindrical inner core, means detachably securing said mold sections to each other, said means including U-shaped members secured to said mold sections and a channel-shaped member engaging said U-shaped members, substantially cruciform-shaped sets of core pieces secured to said outer shell, each of said outer mold shells being formed in parts hingedly secured to each other, said mold shells having converging end portions, aligned slots in said end portions, and a divider plate extending between said mold sections.
